What is Plagiarism?

Plagiarism means copying and in this digital world it indicates stealing content from other websites or source. There are millions of websites available online and the content stealing is one of the biggest problems for online publishers. Many website owners simply steal the content from other websites, rewrite and publish as their own. In addition, there are also other problems like duplicating student projects, essays and published eBooks.

Why You Should Check Plagiarism of Your Articles?

Frankly, there are no need to check plagiarism if you write the article on your own. However, it is not possible for you to publish the content consistently especially when running multiple blogs. In addition, you may also inherit some sentences from other sites unintentionally.

  • Check plagiarism to make sure you do not publish duplicate content like any other existing websites.
  • When you purchase content from freelancers, it is necessary to verify the content is unique before you pay for them.
  • Unique content helps to add value in the entire ecosystem and builds trust with your readers.
  • There are possibilities that your website can rank better in search engines like Google compared to copycat websites.

In addition, students can use the plagiarism checker to confirm the essays and project documents are unique and not stolen form some books.

You may wonder, what is the difference in searching with Google and using this tool. Google will limit the keywords to 32 when searching and our tool allows you to search with 1000 words. This is sufficient for testing the entire article in most cases. If your article is more than 1000 words, you can split into two sections and check two times.
